PATENT EEIcE.

WILLIAM L. AUSTIN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO BURNHAM, WILLIAMS t COMPANY, OF PHILADELPHIA, PENN- SYLVANIA, A FIRM.

LOOSE-WHEEL STRUCTURE.

SPECIFICATION forming part of Letters Patent N o. 770,147, dated September 13, 1904.

Application led January 27, 1904. Serial No. 190,862. (No model.) I

To all whom, t may concern:

Be it known that I, WILLIAM L. AUSTIN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Loose-Wheel Structures, of which the following is a specification.

My invention relates to certain improvements in wheels and axles in which a wheel is loose on the axle.

My invention is especially applicable for use in connection with the truckillustrated in the patent granted to me on the 2d day of February, 1904, No. 751,243.

The object of my invention is to improve the means of mounting' the loose wheel on the axle.

In the accompanying drawings, Figure 1 is a view of an axle, showing the wheels in section. Fig. 2 is an enlarged view of part of Fig. 1, and Fig. 3 is a view of a modification.

A is the axle, having reduced portions a a, which are mounted in the usual journal-boxes.

C is a wheel of any of the ordinary forms, which is secured to the axle.

B is a wheel loose on the axle. This wheel is made in two partswa hub or center section 5 and a rim-section b/ secured together by rings b2; but it will be understood that the wheel may be made in a single piece or made in any well-known form, as I make no claim to the particular type of wheel.

The axle is reduced at a', forming a shoulder a2, and is reduced at a3. Shrunk on the portion a of the axle is a ring D, resting against the shoulder a2.

The hub of the wheel B is mounted between the ring D andaring E, shrunk on the portion as. This ring has an internal flange e, which rests in a groove a4, so that when the ring E is shrunk upon the axle the internal fiange enters the groove and retains the ring in place.

The wheel Bis preferably provided with a bushing f, as shown.

I have illustrated in Fig. 2 a lubricatingpassage c' and an ordinary form of lubricator I, screwed into the mouth of this passage, so as to lubricate the bearing between the wheel and the axle, as it will be understood that the wheel can freely turn on the axle, the object being to allow the axle and wheel to turn independently when the car, for instance, is passing around a curve.

In Fig. 3 I have shown the inner ring Din the form of a flange formed on the axle instead of being a separate ring shrunk thereon.

By my invention I simplify the means of attaching the wheel to the axle and provide an attachment which dispenses with the use of bolts or other fastenings which are liable to become detached.

I claim as my invention- 1. The combination of an axle having a reduced portion, a wheel mounted on the reduced portion, an inner ring shrunk upon said reduced portion, a groove in the axle beyond theouter face of the wheel, a ring having an internal flange shrunk upon the axle and confining the wheel, substantially as described.

2. The combination of an axle having two reduced portions and having a groove between the two portions, a wheel mounted on the axle, an inner ring shrunk upon one reduced portion, an outer ring having an internal iiange shrunk upon the other reduced portion, the iiange of the ring entering the groove in the axle, with a wheel rmounted loosely on the axle between the two rings, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WM. L. AUSTIN.
